I w fizz w 4 TTORNEY United States Patent This invention relates to hoods for kitchen ranges,

and more particularly to a simple, economical and attractive hood capable of long and efficient life in service.

According to'prior art practices, such hoods have conventionally been fabricated from a single flat sheet of metal resulting in large scrap losses and an expensive construction not readily adaptable to unusual contours ,such as are frequently needed to accommodate various shaped kitchens.

Accordingly, a primary object of the present invention 1s to devise a novel hood which may be fabricated in various sizes and shapes with a minimum scrap loss and by the use of a single set of dies.

Another object of the invention is to avoid the necessity of a layout on a fiat sheet of material.

A further object of the invention is to devise a hood which may be economically fabricated in standard sizes by fabricating a plurality of such hoods in a single sequence of steps.

Still another object of the invention is to provide a top panel which can be entirely or'partially eliminated to afford an outlet from the hood to a vent passage and which may be formed of a relatively inexpensive material as compared with that of the visible portions of the hood.

The foregoing and other objects and advantages of the invention will become apparent from a consideration of the following specification and the accompanying drawings, wherein:

"Describing the invention in detail, a preferred embodimentof the novel hood 2 is illustrated in Figure 1 mounted beneath wall cabinets 4 above a conventional cooking range .6. As best seen in Figure 2, the novel hood comprises a rear .wall16 integrally connected to side Walls 10. The ..sidewalls 10 are integrally connected at their forward Patented Sept. 1, 1959 extremities to spaced front walls 14 which converge toward each other from the side walls 10. All of the walls 6, 10, and 14 are preferably flanged as at 16 and reflanged as at 17 (Figure 8) to afford a smooth bottom .edge which is neat in appearance and safe to clean. The

upper edges of walls 6 and 10 are flanged as at 19 for a purpose hereinafter described.

The upper edges of front walls 14 are unflanged and slope downwardly from the side walls 10 as at 16 (Figure 5) to their forward edges 18 which are preferably approximately vertical. A cap 20 having converging lateral edges 22 is welded or soldered therealong as at 23 (Figure 2) to the edges 16 of the front wall 14, said cap having a downwardly and forwardly sloping panel 24 formed with the before-mentioned edges 22 and flanged at the upper extremity thereof as at 26. The flange 26 is preferably soldered or welded along the lateral edges thereof to the forward edges of the side wall flanges 19, respectively, as indicated at 27 in Figure 2.

The panel 24 merges at its lower extremity with a substantially vertical front panel 28 which is approximately the same height as the forward vertical edges 18 of the walls 14 and is welded or soldered thereto as at 30' (Figure 2). The lower edge of the panel 28 is flanged as at 32 and reflanged as at 34 for the purposes heretofore described in connection with the corresponding flanges 16 and 17 of walls 6, 10, and 14.

A top panel 36 (Figure 8) is preferably seated against the underside of flanges 19 and 26 which are preferably horizontal and are soldered, welded or otherwise secured to said panel 36.

As best seen in Figure 1, the entire hood 2 is adapted for attachment in any desired manner to the underside of wall cabinets or other structure overlying a cooking range, to trap or collect the heat and vaporized greases of cooking. If desired, a hole may be provided in the top panel 36 or a portion thereof may be cut away prior to assembly to afford convenient connection for a fan or blower which draws such cooking heat and vaporized greases into a conduit or vent and discharges. them at a point externally of the kitchen.

Referring now to Figure 3 and describing the fabrication of the novel hood, it will be seen that a sheet of any suitable material such as stainless metal or plastic is flanged in the usual manner as for example in a conventional flanging press to define the flanges 16, 17, and. 19. These flanges are then notched as at 38, each notch in the flange 19 being aligned with a corresponding notch of flanges 16 and 17. Each notch 38 also defines approximately perpendicular edges 40 (Figure 3) of the related flange, said edges being about equal in length to accommodate mating thereof at 42 when the sheet of metal or plastic is bent to the shape shown in Figure 4.

Either before or after the bending step, the front walls 14 are cut as shown in Figure 5 to eliminate their flanges 19 and to form the before-mentioned top edges. 16, which, after said bending step, slope downwardly and forwardly from the side walls 10 and which converge toward the free ends 18 of the front walls 114 remote from their connections to the side walls 10.

The cap 21 is similarly formed by flanging and cutting operations and is welded or soldered along its lateral edges 22 to the edges 16 of front walls 14- and along the lateral edges of front panel 28 to the mating edges 30 of the front walls 14. The cap flange 26 is also preferably soldered or welded at 27 to side wall flanges 19 at this time. If desired, the flange edges 40 may also be soldered or welded as at 42 in Figure 4, either before or after the cap is soldered as above described.

Preferably, the final step in the manufacture of the novel hood is to solder or weld the top panel 36 to the flang s 1.9 nd 26, t ou f d i this panel ay be if desired, the top panel 36 may be securedin position at any time after the walls 6 and 10 are formed as shown in Figure 4.

Referring now to the modification of Figures 9, 11 and 12, it will be seen that the novel hood comprises side walls 52 integral with a front wall 54, said walls being preferably formed of a continuous section of prefabricated stock substantially identical in cross section to that of the cap 20, as shown in Figure 7. Thus, each of the side walls 52 and front wall 54 comprises a sloping panel 56 (Figs. 11 and 12), the lower edge of which joins a substantially vertical panel 53 flanged at 60 and reflanged at 62 for a purpose heretofore described in connection with the previous embodiment.

Each of the walls 52 and 54 is also provided with a substantially horizontal top flange or panel 64 for convenient attachment, as by soldering, to a top wall or panel 66 (Figures 11 and 12), and said top panel is also soldered to a top flange or panel 68 of a cap 70 having a substantially vertical wall or panel 72 forming the rear wall of the hood. The panel 72 is flanged as at 74 and reflanged at 76 for the purposes heretofore described.

The hood of Figures 9, ll, and 12 is fabricated by cutting to length a section of prefabricated stainless steel or aluminum stock having the cross section shown in Figure 7. This section is then notched through the sloping panel 56 thereof and through flanges 64, 60, and 62 thereof, as described in connection with the previous embodiment, to accommodate bending to the configuration shown in Figure 9, whereupon the edges of the notches are joined as by soldering at 78, and the cap 7% is soldered at the lateral edges of its flanges 74, 76, and 68 to the rear edges of side wall flanges 6h, 62, and 64, respectively, and the cap 70 is soldered along the lateral edges of its panel 72 to the rear edges of the side wall panels 56. The top panel, if any, is then soldered to flanges 64 and 68, and the hood is ready for installation. If desired, a ventilator hole of any desired size may be provided through the top panel 66, and, if desired, this panel 66, as well as cap 70, may be formed of a relatively inexpensive material such as ordinary sheet steel, inasmuch as these parts ordinarily are hidden from view by abutting walls of the kitchen or its cabinets.

The modification of Figure 10 is very similar to the embodiment of Figures 1 to 8, and corresponding parts are identified by corresponding numerals. In this modification two rear walls 6 are integrally formed at right angles to each other and are integrally formed with side walls It}, the forward edges of which are integrally formed with front walls 14 soldered along downwardly converging edges 16 thereof to complementary lateral edges of a cap 28.

The walls 6, it and 14 are formed of a single section of prefabricated stock identical in cross section with the corresponding stock shown in Figure 3 and are shaped to the configuration of Figure 10 by notching and bending in the manner described in connection with the embodiment of Figures 1 to 8, except that an extra pair of notches 38 are formed in the flanges 16, 17 and 19 to accommodate bending of the rear wall 6 as at 80 to form a pair of such walls at any desired angle to each other. In the illustrated embodiment of Figure 10, the walls 6 are perpendicularly related to fit into a corner of a kitchen below a corner cabinet.

The cap 20 is formed of a single section of prefabricated stock having a cross-section identical with that of the cap shown in Figures 6 and 7; however, the flanges 26, 32, and 34 and panel 24 have been notched to accommodate bending of the panel 28 as at 82. The notches are then soldered as at 84 to complete the hood for installation.

Thus it will be understood that the novel hood may be quickly and economically fabricated from standard prefabricated sections of stainless steel or aluminum stock or from standard prefabricated sections of any other desired material. The hood may also be conveniently designed to the dimensions of the spaces to be covered thereby without the necessity of expensive procedures or materials. Also, scrap losses are held to a minimum and the top panel 36 may be formed of less expensive material than the other portions of the hood which are exposed to view.

An important aspect of the invention is to devise a hood and method of making in which the components thereof may be prefabricated, as by rolling or breaking in sectional lengths, as distinguished from prior art practices wherein the hood is shaped from flat pieces of material.
